Did most dinosaurs have feathers ?

A new well preserved fossil find suggests that feathered dinosaurs may have been quite common.

Palaeontologists have been identifying an increasing number of feathered dinosaur species in recent years. The discovery of a 150-million-year-old theropod in Germany covered in a thick plumage is now helping to cement the view that feathers were likely to be far more prevalent than previously thought. Finding fossils showing feather coverage is difficult however as their preservation requires very specific conditions.

"We need more examples in both non-coelurosaurian theropods, and particularly in the other big dinosaur groups, before we can really speculate that these features are a character of dinosaurs as a whole," said Palaeontologist Paul Barrett.

"Feathers didnít start with birds. Plumage of various sorts - from simple fuzz to the complex structures used for flight - adorned dinosaurs first, and was only later inherited by birds."

Get used to it. Yutyrannus huali was discovered in China a few months ago. Oh, ha, I apologize! I didn't notice!

No worries, I'm just ribbing. We've only gottenso far with coloration, I wonder if there were dinosaurs as vibrantly plumed as some of our modern day birds. Just to nip this off, dinosaurs didn't live in the sea, those were marine reptiles. While they were almost exclusively warm blooded and gave live birth, they did not have feathers. they were also cooler and scarier than their land dwelling cousins. Just saying.

Indeed. I look forward to the next major full-body colouration determination they do. Archaeopteryx has always been one of my favorite dinosaurs, ever since I was young, and I always pictured it being vibrant; almost like a quetzal or something... this year they had to break it to me that it basically looked like a crow. I still love it.

Hey, I like how crows look. Even had a semi- tame one at the shop that'd pick up food left for it. Besides, they travel with Odin. Anything with that company's alright in my book.

After reading through this thread, I think a remake of The Birds might be more fitting...

Hey, my Huginn and Muninn are not common crows. They're Ravens.

At the cellular level, feathers and scales are indistinguishable from each other. Like the rhino horn being made of the same proteins as hair, you can get a very different result depending on Momma nature cooking in her kitchen.
